CAR-AXLE LUBRICATR.

SPECIFICATION forming part of Letters Patent No. @11H/ dated February 3, 1885.

Application filed October 17, 1883,

To all whom it may concern:

Be it known that I, TnoMAs Rollen Gon- DON, a subject of Great Britain, residing at Brooklyn, in the county of Kings and State of New York,have invented anew and useful Improvement in Car-Axle Lubricators, which improvement is fully set forth in the following speciiication and accompanying drawings, in

Figure l is a front view, partly sectional, of a car-axle lubricator embodying my invention. Fig. 2 is a top view thereof. Fig; 3 is a vertical section in line .t a", Fig. 2.

Similar letters of reference indicate corresponding parts in the several iigures.

My invention consists of a lubricator having a frame, a spring supporting said frame, fabric covering said frame, and cushions formed by bending said fabric repeatedly over the traverses of said frame and sewing or otherwise attaching the folds of said fabric to one another.

It also consists of the above devices having the fabric doubled into loops above the traverses and sewed together, as shown.

It also consists in the combination of the aforesaid parts with a depending apron having loose sides, substantially as hereinafter set forth.

It also consists in abase-plate of peculiar construct-ion, in combination with the spring resting thereon and the other parts above referred to.

Referring to the drawings, A represents a metallic frame, consisting of front and rear pieces, a, of downwardly-curved form, and connecting side or transverse pieces7 b.

At the center of each piece c is an eye, o, which extendswertically and opens upward, for receiving the journal or axis of a wiperroller, B, as the bearing therefor, said roller, when the lubricator isin position, being in contact with the car axle or journal.

Depending from and formed with the center of the pieces a are lugs C, to which is connected a coiled spring, D, the upper coil whereof is passed through and secured to said lugs.

E E represent cushions at the top ofthe frame, which are formed of felt or other suit- (No model) able fabric, continuous of strips F, likewise formed of felt or other suitable material, said strips surrounding the coils of the spring.

Each cushion is formedby folding the felt inwardly over the side piece, b, as shown at my, then connecting the thicknesses of fabric below said side piece by astitch or stitches, n, then turning the felt inward and upward at o, then turning it outward again over said side piece and the felt thereon at p, then turning it down and stitching all these thicknesses through at q. The apron K, hereinafter described,l is connected to this outer thickness by stitches i".

To improve the cushion l may form a loop, s, in the outer thickness of it above the side piece, b, as shown at the vleft side of Fig. 1, and stitch this loop through at the base, as shown at t. This construction is not necessary, however, and the cushion at the right side of Fig. l has no loop.

To the rear piece, c, of the frame is connected a ilap, G, offelt or other suitable material, and its ends are secured to the rear of the cushions E, the flap forming adish-shaped receptacle when in use. The lower ends of the side strips,F,are stitched to the bottom coil of the spring, and to said coil is also connected a metallic plate, H, which is formed with lips H', which are turned up from the edges of said plate and embrace the coil, thus iirmlysecuring said plate to the spring.

Vhile I have described the connections of the cushion, rear iiap, and side strips with the frame and spring by means of stitching, it is evident that the same may be accomplished byriveting.

To the roller B are secured brushes @which project radially therefrom, and are of such length as to come in contact with or wipe the inner sides of the strips F andy the surface of the axle or journal.

The lubricator is applied in position by compressing the same, so as to be fitted between the-floor of the journal-box and the axle or journal, the plate H resting on the door7 it being noticed that said plate permits the ready introduction of the lubricator into the box, the rough floor whereof affording an obstacle t0 the passage of the lower coil of the spring lOO and bottom edges of the side strips, which, however, is avoided by the plate H, which readily moves over the lor, removes the spring andv strips from contact therewith, prevents grinding action of the door on said spring and strips when the car is in motion, and also prevents contact and wearing action of the brushes on the tloor, the smooth surface of the plate not materially affecting the ends of said brushes, the lubricant being also taken up by the brushes in a cleaner and better condition. As the side strips are immersed in the lubricant and absorb the same, the cushions, which are continuous of the strips, become saturated with the lubricant, and thus supply the axle 'or journal there with, it being noticed that the cushions are but lightly in contact with the aXle or journal, as the ends of the roller B press rmly against the same, by which provision the cushions are prevented from heating, gumming, matting, Src. rIhe rear iap, G, is adapted to wipe and lubricate the journal and its shoulder, and forms in a measure a receptacle for catching the lubricant that drops from the journal and feeding it to the cushions, loss ofthe lubricant at the rear being prevented. The end iiap furthermore serves as a guard for preventing the entrance of dust, grit, the., into the box and passage ofthe same to the journals. The side strips also form an inclosure for the lnbricator, so as to restrain the lubricant from being thrown about and out of the box by the motions of the car and actions of the revolving brushes or bristles, and prevent dust, grit, &c., reaching said brushes, the cushions, and the journal.

K represents a depending apron, which is secured to and extends around the sides and rear and, it' desired, the front of the lubricator. As the side strips are separate, a space is left between, and thus when the lubricator is compressed said space is closed or covered by the apron K, preventing dirt, grit, Src., entering the lubricator from the rear. Again, as the side strips, F, are separated at front or rear, or both, when the spring is compressed there is no material of said strips to gather or `fold in the pathof the apron K and iiap G, the sides of said apron being free or loose, so

that the apron rises and falls without interference of the side strips, F. As the cushions E E are formed of fabric doubled on itself, should the outer layer be worn away, the inner layer presents a fresh surface, thus increasing the wearing qualities of said cushion. At the left-hand side of Fig. 1 the cushion is elon' gated and stitched through, thus increasing the surface of the same. rlhe eyes c extend into the lugs C, and are thereby deepened for thejournals of the roller B.

I am aware that the construction and combination ofniy spring-roller frame and brushes are old, and also that these parts thus combined have heretofore been provided with side pieces or casings of textile fabric. These constructions and combinations I therefore do not claim in this application; but,

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-.

l. A lubricator having a fran1e,'spring, cush ions, and a wiper, the fabric of the cushions being doubled and bent over the traverses of the frame and looped and stitched through above said traverses, substantially as and for the purpose set forth.

2. The frame and connected spring, in coinbination with the cushions E, the end flaps, G, separated side strips or skirts, F, and the depending apron K, having loose sides, substantially as and for the purpose set forth.

4. In a lubricator, a frame, A, provided with a lug, C, in combination with a roller, B, journaled in said frame, a spring, D, attached to said lug and supporting said frame, and a base-plate, H, provided with raised lips H', for retaining the spring in place, substantially as set forth.

4. In combination with a spring-supported frame and cushions formed thereon, an apron, K, which is exterior to said frame and cushions and rises above the same, said apron being sewed to said cushions, substantially as set forth.

THO. R. GORDON.
